1）There are a total of 8 serial ports for the assessment board, where UART1 is used as a debugging serial port, UART 6, UART 7, and uart8 are used as LCDs, so there are 4 serial ports for testing.<br>
+
-------------------------------------------------------------------------------- 
−
2）The operating file corresponding to UART1 is / dev / ttymx0, uart2 corresponds to / dev / ttymxc1, and so on.<br>
+
* Looking forward to communicating with you for more functions and field applications.
−
3）Take uart2 as an example, which is tested by spontaneous self-collection.<br>

===Test method ===
+
--------------------------------------------------------------------------------
−
1）Short uart2_rxd and uart2_txd to see how it works, corresponding to the 11 and 12 legs of P7 respectively, short them.<br>
+
</pre>
−
2）Execute test command:/home/root/my-demo/linux-4.1.15/uart_test.out /dev/ttymxc1<br>
 
−
3）Test results are shown below to indicate that the test passed<br>
 
−

4）Other serial port tests are the same as the uart2 method.<br>
 
−
 
 
−
== '''SPI Test''' ==
 
−
===Test instruction===
 
−
1）There are 2 SPI channels in the evaluation board, and the corresponding device file of SPI1 is /dev/spidev0.0.The file for SPI2 is /dev/spidev1.0.<br>
 
−
2）Taking SPI1 as an example <br>
 
−
 
 
−
===Test method===
 
−
1）Shorten the 24 and 26 feet of P8.<br>
 
−
2）Execute test command:/home/root/my-demo/linux-4.1.15/spidev_test.out -D /dev/spidev0.0<br>
 
−
3）Test results are shown below to indicate that the test passed<br>
 
−
[[File:MY-IMX6-ek140-L41115_1.7.2.0.jpg|520px]]<br>
 
−
Note: The SPI2 test method is the same as SPI1(ie, the same above).<br>
 
−
 
 
−
== '''CAN Test''' ==
 
−
===Test instruction===
 
−
There are two ways of CAN in the evaluation board, because the test of CAN requires the welding of CAN's transceiver chip. This assessment board does not have the welding of CAN's transceiver chip. If testing is needed, please refer to the test manual of MY-IMX6-EK140P.<br>

2）GPIO serial number calculation method. For example, SN VS_TAMPER 2, look at the arch/arm/boot / dts/imx6ul-pinfunc. H file and you can see that it belongs to the second IO of GPIO Group 5, IO serial number =(GPIO Group -1) * 32 + IO. So SN VS _ TAMPER 2 =(5-1) * 32 +2 = 130.<br>
 
−
 
 
−
===Test method===
 
−
1）Set the IO number of the GPIO to test：OUT_IO_NUMBER=130<br>
 
−
2）Lead out GPIO：echo ${OUT_IO_NUMBER} > /sys/class/gpio/export<br>
 
−
3）Set the GPIO direction:echo out > /sys/class/gpio/gpio130/direction。<br>
 
−
4）Control output electrical level：echo 0 > /sys/class/gpio/gpio130/value<br>
 
−
:After executing the command, the 32 pin of P8 can be measured with multimeter as low level.<br>
